CARLO R. TAYLOR, OF SOUTH BEND, INDIANA, ASSIGrNOR OF ONE-HALF HIS RIGHT TO JOHN GRANT, OF CHICAGO, ILLINOIS.

IMPRovEMENT IN HARRows.

Specicatiou forming part of Letters Patent N o. 192,094, dated June 19, 1877 application filed June 5, 1877.

To all lwhom it lmay concern Be it known that l, CARLO R. TAYLOR, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and usef'ul Improvements in Harrows; vand I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable4 others skilled in the art to which it pertains to make and use it, reference being had tothe accompanying drawings,

:held a suitable distance apart by means of cross-bars B B, which form the harrow-frame, and is to have the teamattached in one corner, as at a. C C represent dat coiled springs, of any desired number, and attached to the beams A. One end of each spring C is attached to the under side of the beam at such an angle that the line of the spring, as it coils upward and forward over the beam, and then downward under the same, will be on a line parallel with the lille of the draft. On the lower end of the spring C is attached a shoe, D, of substantially the form shown in the drawing, and in such a manner that a slot or opening will be left at the extreme end of the sp1-ing sufficiently large to admit of the blade Gr, which forms the barrow-tooth. The lower end of the bladeG is rounded, as shown, and I the blade has a central slot, b, running longition of the coiled springs C serves as a gage Y for regulating the depth of the teeth.

It will be noticed that as the harrow moves forward, and the blades catch in the ground, the tendency is tocoil the springs more and more, increasing their tension in proportion to the resistance, and thus insuring a perfect and even work vof the barrow over the ground. l

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The flat adjustable blade G, attached to a coiled spring, and forming a harro\.\.-tooth, as herein set forth.

2. The combination ofthe coiled spring C, shoe D, and adjustable. blade G, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of June, 1877.

C. R. TAYLOR.
